Through the research we have been carried out, it was aimed to identify the types of not levelled and modeled sandy soils, to determine the physical-mechanical, hydrophysical and chemical properties and, based on them, to ascertain the changes that appeared as a result of the modeling works, from a morphological point of view, in regarding the particle size composition and implicitly texture, density, bulk density, aeration porosity, total porosity, hydrophysical indices (hygroscopic coefficient (HC, %), wilting point (WP, %), water field capacity (WFC, %) available water capacity (AWC, %) yet, also, chemical properties (humus, soil reaction, bases saturation degree, supply of nutrients). Through a comparative study of the data obtained with the 4 identified sandy soil types (unleveled typical sandy soil, leveled typical sandy soil (uncovered), unleveled mollic sandy soil, leveled mollic sandy soil (covered), there have been observed an obvious influence of the leveling work on the mentioned properties that were found.
